LOAFTFORMING MACHINE.

Specification 'of Letters Patent.

Patented Oct. 13, 1908 Application filed August 12, 1907. Serial No.388,189.

To all who-m 'it may concern:

lie it known that I, CHARLES H. OVER- it.\.\|r, a citizen of the UnitedStates, residing at Cincinnati, Ohio. have. invented a new and usefulInil'irovemcnt in Loaf-Forming Machines, of whichthe following is aspeci tication.

My invention relates to loaf forming machines of the class adapted tothe use of bakers, and the objects of my improvement are: to rovidemeans for automatically forming oaves from predetermined quantities ofdough; to provide adjustable means for rolling the dough into a sheet ofpredetermined thickness; to provide automatic means for coilino thesheet into a roll; to provide adjustable means for molding the roll thusformed into predetermined size and shape; to rovide the machine withremovable and interchangeable mold boards; to provide' means forautomatically delivering the rolls to the mold board, and to provide simle and durable construction combined wit i facility of o eration andeiiiciency of action. These objects are attained in the followingdescribed manner, as illustrated in the accompanying drawings, in whichFigure 1 is a side elevation showing the driving mechanism for thedifferent rolls; Fig. 2 a vertical diametrical 4section'of the casingwith arrows to indicate the direction of rotation of the rollerstherein; Fig. 3, a t'ront elevation with parts removed and parts insection on the line a-aof Fig. 2; Figs. 4 and 5 a plan and sideelevation reintermediate roller and Fig. 6, a vation of the curved loafguide.

In the drawings, 1 represents the casing supported on frame or base 2and formed with side walls 3, witha hopper 4 in its top portion and withan o ening 5 ont elearc concentric with the a ron roller and to-r wardthe feed roller 7. ollers 8 and 7 are rotated in opposite directions andfrom the spectively of an adjustable bearing for the driven pinion 12 bymeans of gears 13 and 14. Rollei' is rotated from roller 7 and in anopposite direction by means of .gears 15' and 1G and roller and in thesame direction by means of a chain and sprocket wheel connection 17therewith. All of said rollers are rotated at the same peripheral speed.The' usual Scrapers 18 and 19 are provided for the feed rollers 6 and 7.An idle apron roller 20 is journaled in bearings 21. which areadjustably secured to the casing and an endless apron 22 carried by theapron roller S travels thereove-r and under the small guide roller 23,and also under the apron guide board 24 which is secured between thewalls of the casing.

A yoke 25 located on the outside of the casing is pivotally lnounted onthe extended ends of shaft 26 of roller 6, the front portion of saidyoke extends across the front end of the casing and is provided with aprojecting casing is pivot-ally mounted on the extended arm 27 whereon aweight 3() is adjustable. The legs 28 of the yoke form bearings for therespective ends of the shaft 29 which is e.\' tended through slots 31formed in the side walls of the casino and carries 4a forming roller 32.A sprocilret wheel 33 on shaft 29 is driven by a chain 34 from a wheel35 on shaft 26 for rotatinv' roller 32 at the saine peripheral speed asthat of rollers 6, 7, 8 and 9. Branch arms 25 near its pivotalconnections with shaft 26 carry the respective ends of shaft 37 which ismovable in slots 38 formed in the side walls of the' casing, and whereonan idle tripping roller 39 is mounted within the casing.

A curved loaf guide 41 formed with ears 42 which are movable in verticalslots 43 formed in the opposite walls of the casing is verticallyad'ustable within the casing by means of adjusting screws 44. A moldboard 45 removably secured at its rear end to the guide 41 by a pin 4()or other suitable means formsa forward continuation thereofr a shortdistance below the endless apron 22 and is adjustably supported near itsfront end on adjusting screws 46.' Said mold board may be transverselyconcaved on its upper surface as shown in/Fi 3 for formn oval shapedloaves gas shown dotted lines) or a number of mold boa v 9 is rotatedfrom roller 8 36 extended from the yoke tially co'unterbalaneing theweight of the '1 sired.

sheet by the feeding rollers 49 to spiral rolls of with ditl'iwentsurface patterns may be used interehangeably to 'lorm loaves ofdifferent shapes as desired.

ln operation, the proper quantity of dough for a loafl is placed in thehopper and moves the idle tripping roller 39 in a forward direction inits passage thereunder. It thence passes lbetween and is rolled into athick and 7, which sheet is continued and rolled thinner between rollersT and t). As the sheet; of dough is being delivered on the apron fromroller 9 it is carried thereby partly around roller S and in contactwith the forming roller The action of rollers 9, 8, and 32..se..i'i'esto form the sheet of dough into a` spiral roll as shown at 47 in lVhenthe lmnp of dough for another loaf is placedv in the hopper the trippingroller is again moved thereby in a forward direction and in an arc con#centric with roller G whereby the yoke is oscillated' on its pivotsuliiciently to raise the 3) for the passage thereunder forming roller Lof the spiral roll 47. The action of the apron rolls the spiral roll 4Tin a. forward-t direction in contact. with the curved guide l and themold board whereby it is formed into the desired shape and. compactnessand l delivered 'in the curved apron 4:8 ready for remo.'al to the oven.In this manner the lmnps'of dough successively delivered in the hoppermove the tripping-roll and actuate the yoke with the forming roll todeliver the spiral roll formed from the preceding lump into the passa-ge49 between the apron and the curved guide and mold board. The 'dough maybe delivered to the hopper if desired directly from a dough dividing andsealing machine. The apron 0fnide board 24' prevents the lifting of theendless apron during the passage of the spiral roll thereunder along themold board. The thickness lof the4 sheet of dough may be 'regulated asdesired by the adjustment of roller 9 in relation to roller 7. Thethinner said sheet of dough is made the -rnore compact Will be spiralroll made therefrom. The weight 30 may be adjusted on the arm 27 of theyoke for partripping and forming rollers thereon as de- The curved guideand the mold board may be adjusted by means of the adjusting screws toadapt the depth of passage different size. The face of pressure roller 9may be knurled or covered with canvas if desired.

Having fully described my improvement,
